SASH R STORE-FRONT CONSTRUCTION'.

Application led January 26, 1924. Serial No. 688,855.

To all whom/1f may concern.-

Be it known that I, ARCHIBALD H. DAVIS,

a citizen of the United States, residing at Lincoln, in the county of Lancaster and 5 State of Nebraska, have invented certain new and useful Improvements in Sash or Store- Front Constructions, of which the following is a specification.

This invention relates to sash or store front construction.

The object of the invention is to provide an improved sash or store `front construction which will be strong, durable, and self-contained,.so that it may be used by itself without requiring the use of other reinforcing materials, such as stops, sills, and jambs of wood or, possibly metal, thus minimizing expense otherwise involved for material and installation when used in store front construction.

Another object is to provide an improved sash construction adapted to be directly applied to the pane of glass without requiring its attachment to other materials or frame' pieces when thus used so that the construction alone will 'serve its purpose vas a sash for windows.

A further object is the provision of an improved sash or store front construction utilizing a novel fulcrum principle or joint between the sections thereof by which the pane or plate of glass may be readily Set in one section and, thereafter, the other section applied and, by the use of tensioning means l and by a fulcrum action, the movable section made to bear against the pane or glass and the twosections to securely hold the pane or plate glass with a firm, and yet morel or less resilient, grip.

The utilization of the improved .joint or fulcrum arrangement in. my invention en.

ables an adjustable leverage action to be obtained without dependence on extra members or frame pieces and adapts the Sections to glass of any thickness and to the variable thicknesses at diiferent points in the same piece of glass. Furthermore, the utilization of the improved ulcrumV joint between the sections and the tensioning means `therefor enables the desired clamping action or leverage to be obtained by setting and adjustment only on the outside of the sash or store front' which, frequently, -is the only accessi4 ble side.

,55 I am aware that it has been proposedv to provide a swinging section in sash and store front constructions but so far as I know I am the first to provide a sash or store front construction having sections which are jointed or tulcrumed together according to the principle of my invention 'and adapted to be assembled and tensioned from the outside.

It is my purpose to construct the sections .of the sash or store front of relatively heavy dent easily in vtransportation or when beingl handled, nevertheless will have suicient' resiliency to adjust itself to the ffulcruming action and to the pane or plate ofglass so that the latter will be rigidly held but without the necessity of employing special cushioning means.

Other objects .and purposes of the invenlowing description. It is to be understood' that the invention is susceptible of modication and while I have described'certain partion will appear more fully from the fol- -i ticular embodiments thereof and have shown Y them in the accompanying drawings, it is possible to embody the principle of the invention in other forms.

vIn the accompanying drawings: Figure l is a detail perspective, partly in section, showing an embodimentof the invention adapted for store front construction. Fig. 2 is a detail perspective, broken away and in section, showing one of the sections of the construction.

Fig. 3 is a similar view of the outer or fulcrumed section. i

Fig. 4 is a detail cross section showing a modification.

Fig. 5 is a view like Fig.. 1 showing a modification employing a clip plate.

Fig. 6 is a view like Fig. 2 of the inner section of the form of Fig. 5.

Fig. 7 is a view like Fig. 6 of the outer section of the construction of Fig. 5; and

Fig. 8 is a detail sectional view `ofthe i clip plate of the construction ofFi 5.

It will be understood that alll orms `of kthe vinvention hereinafter described and which are shown in the drawings ma be used merelyv as sash for windows wit out resort to otherpieces, or, these constructions in Figs. 1, 2, 3, the inner or pane seating section 1 is of metal of suitable gage for the requisite rigidity as distinguished from thin gage stock which has heretofore been commonly used. This metal may be eX- truded brass or bronze, orcold-rolled, or drawn. It is not the purpose of the invention to provide metal which will easily yield, as does thin stock such as heretofore commonly used, because thin stockhas the charaeteristic of .yielding at undesirable lpoints as well as at desirable points. rlhe gage of metal employed is such as to afford continuous pressure on the glass instead of merely,l at screw or bolt points, as is the case with light metal and which results in breakage. v

The sectionl is of open, box,or troughlike form,provided with a flat back 2, flat base 3, and short frontf4. The back 2 has a trough-like upper part Whose inner wall 5 is flat-and ladapted to provide a suitably high and properly firm abutment for the pane of glass 6 so that the' latter may be held against theabutment by considerable pressure in themanner hereinafter set forth. The channeled :upper-end of the back- 2 is provided with holes 7 at suitable pointsV to provide for ventilation and drainage and thefront 4`hassimilar holes 8 for the same purpose.

" Any suitable'isupport or cushion 9 is provided inside ofthe section 1 for the glass 6 to rest against, or upon, as is common 1n sash and vstorefront constructions. The upperpart of the front wall 4 is provided with an inwardly .projecting flangev 9 whose-upper surface isgrooved or channeled as shown at 10,suchchannelextending the full length of the iiange 9 and, in cross sectional'shape, being preferably struck in the arc of a circle toatford the'requisite bearing or fulcrum pivotally mounted clamping section 11. The flan e 9 has an extension 12 pointing downward tion to the section 1.

The upper part of the section" 11 is of compound'curve shape in cross section, its

upper partll being adaptedto bear against the pane `or glass 6-and lby reason 02E- the curvature at 12, there is no tendency to chip or crack the pane 6 eventhough the pressure exerted by the section 11 on the pane is very considerable. Furthermore, the curvature at 11 enables the section 11 to be adjustedtightlygagainst the pane 6, in the manner hereinafter set forth,'with a mor-eer less Wedging action, without injury tothe pane. 'p v The section 11 is rounded throughout its length'as shown at 13, this part bemg cross 1y and inwardly in rela--v sectionally of substantially the same, curvav ture as the seat or fulcrum 10, in which it rests and on whichv it is adapted to turn or fulcrum vwith a knuckle-like action. The section 11 lias a bent part 14 throughout its length which is substantially U-shape in cross section, being .adapted to receive the flange 9 when the sections are assembled. The part 12 of the iiange 9 fits the U-shaped part 14 in such manner that the section 11 is guided in its movement when it is being adjusted and is kept on its seat 10. Furthermore, the provision" of the parts 12'and 13 enables the section 11 to be readily inserted in the section 1, after the pane 6 has been seated on the cushion 9( and then to be connected up and adjusted in a manner which will now appear.

The section 11 is -providedwith screw holes 15 at different points of its depending part 16. y

The front 4 of the section 1 has openings I 17 which are countersunk.

Screws 18 having rounded under surfaces on their A heads, pass loosely through the holes f17 and are engaged with the screw threaded holes 15. ,A

The outerpart of each screw threaded opening 15 is flared so thatthe rounded tip of the screw 18 can readily center in the opening and easily catch the screw threads.

After the pane or glass 6 has been set on the cushion 9, the section 11 is dropped inside of section 1 and caught on the fiange 9 which enters the channel 14; thus the section 11is easily seated on the seat 10i# Due vto the fact that the screws 18 can be moved about in the holes 17 and because of the flared constructionof the screw threaded `holes 15, the tips of the screws readily en- Aage the screw threads ofholes 15.vv Then, y turning the screws 18, the depending part 16 is drawn towardthefffront 4.and the part 11 is drawn rmly-against'thepanera 'im' meanwhile, the rounded part13oftheysection 11 slides or rocks or'fulcrumswon the channeled partlghutthe section V11 cannot become unseated .':beeause'the flange' 12 isv received in, guided by,r the channeled part 14. Thus, the section 11 is drawn with considerable tension against the pane store front. Such holes andV screws arej' necessary when f used as a sash in store front construction. l

In Fig. 4 the/mannebf nfulcruming the'V the section 11. The rounded part 13 of' the section 1.1 is adapted to bear `against the top of flange 9. Screws 18 are provided. The upper part of the section 11,

where it is adapted lto bear on the pane 6 is rounded and bent downwardl'yat 11 instead of upwardly and outwardly.

That` embodiment of 'the invention dis-v closed in Figs. 5 to 8, inclusive, employsl section 1 and 4section 11, also screws 18,

but themanner in which the section 11 is fulcrumed is modified is employed. l

The sect-ion A11 is provide` 11 which bears on the`1-pane 6 and, at its -lower end, it has a channeled part 14 which engages the iange 9 of sectionil, the joint thus provided constituting a fulcrum by which the section 11e-is enable to be rocked on section 1.

'The clip plate 22 has screw threaded,

countersunk openings 15 to receive the screws 18. Said clip plate bearsagainst the channeled part 14 andv holds it in engagement withv the flange 9". The upper end of the clip plate 22 is engaged with the lange'llf. It will be observed that by tightening the screws 18,I the clip plate is forced against the iange 11" and against the channeled part'llf.

In each of the forms ofthe invention described and illustrated, the section 11. is fulcrumed on the section l and screw` means is employed to adjust the section 11 on its fulcrum, beside which there is an interlocked relationship existing between the sections 1y and 11 so that the section 11 cannot Work oi, of its fulcrum.

I claim:

1. In a sash or store front construction,-

the combination rwith a pane-receiving section having a front part provided with an inwardly `projecting flange, ofa pane- .cla'mping section having and a clip plate 22 j and: means for adjusting said clamping secdi'with a flangextion to tension it against the pane.'
